I've played Heart Gold in Japanese illegally, it seriously isn't hard. Moves are easy to recognize, Pokémon are always a surprise, it's like asking to shift without telling the Pokémon.

As for staryline, yeah he may get stuck but there are probably already Japanese at the end of the game, won't be long before online guides and walkthroughs come out. I'm sure someone will have translated it by then, or use some translate page feature.

Castlewars , blind run isn't that hard. That's how I used to play pokemon as a child because I only knew a few basic words in English. I would play Japanese versions of the games too, but I wouldn't understand a thing in the story and playing the english version after you beat the Jap one just to know the story is stupid and since as much as I want to explore the new Unova I want to know what happened to N and all the others. I really hope that they realese it at the end of Summer because school starts at September 1st and I wont be having so much free time.

I remember playing Pokémon Black blindly and with no knowledge on how to read Japanese. That's probably a little harder than playing the sequel. It was an all new generation with new moves, new Pokémon, completely new region, new characters and plot points I wouldn't have had a hope in hell understanding. I still enjoyed my playthrough of it, but it took away the surprise of everything when it was finally released over here.

I'm going to wait until the EU release of the game this time, so the bigger this thread gets, the less I'm going to pay attention to it.
